Queen humiliates Kate -- It's a curtsey controversy!

Off mock ad, Elizabeth takes a real jab

The Queen is knocking Prince William's wife down a peg or two, courtesy of recently released protocols. These protocols dictate how Kate and other royals behave. Off a buzzy mock ad, these revised rules are yet another reminder to the young duchess: You were born a commoner. And don't forget it.

Unlike the TV spot where the Queen mocks Kate, these protocols are no joke.

The cover of the Life & Style Weekly's July 16 issue screams: "The Queen Humiliates Kate."

For those of us Yanks across the pond, these protocols establish how you behave around other members of the royal family.

They also indicate where you fall in the royal pecking order.

With changes to these rules as an indication, Queen Elizabeth doesn't think all that much of Duchess Kate.

The Daily Mail reports a document meant for "royal eyes only" is said to "clarify" Kate's royal status.

By way of the U.K. paper, Kate must, "as a former commoner," show reverence "to the 'blood princesses.'"

What does this mean?

Well, the 30-year-old must quite literally curtsey to the other princesses.
